My present invention relates to improvements in snow removers of the roadwayexcavators type and mounted as a wheeled attachment at the front of an automotive vehicle, as a truck, for clearing the roads, streets,'and highways of snowwn carrying out my invention I utilize an attaching frame for su portin the implement at the front of the ve lele an this. frame has pivoted there- 0 in an adjustable and tiltable carrier-frame upon which are supported the excavators, conveyers and operating parts. The excavater is of the rotary screw type disposed transversely of the front of. the veh1cle and an upwardly inclined, longitudinal conveyor of the endless belt type is utilized for elevating and laterally delivering the snow at one or the other side of the road. Power, and operating means are carried upon the tiltable m table or platformY and manually operated ed P means are utilized for tilting the table to adjust the implement with relation to the surface of the roadway, and for adjusting the position of the wheeled supports of the implement in accordance wit the position of the implement.

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed. In the accompanying drawings l have illustrated one example of the physical embodiment of my invention, wherein the parts. are combined and arranged according to one mode I have thus far devised for the practical application of the principles of my mvention. v

Figure 1 is a top plan view of the implement, partly broken away for convenience of illustration, and attached at the front of an automotive vehicle. Figure 2 is an enlarged detail view of the'manually operated means for tilting theV implement. Figure 3 is a view in side elevation ofthe implement of Figure 1 on'a reduced scale. transverse sectional detail view at line 4-4 of Figure 3. Figure 5 is a transverse sectional view at line 5-,5 of Figure 1. Figure 6 is a. sectional view at line 6 6 of Figure 1 arts being broken away for convenience of 1llustration. Figure 7 is a top plan view of Figure 4 is a c a mount for one of the two caster Wheels of the implement, and Figure 8 is a side view of the wheel and its mount.-

As before stated, the implement is attached to an automotive vehicle, as a truck 1 having 55 the-usual wheels, one of the steering wheels being shown at 2, and the attaching frame of the implement includes a pair of side bars 3 and 4 of I-beams extending longitudinally at the front portion of the vehicle. These side bars are attached -to the frame or chassis of the vehicle by the use of U-bolts 5 and plates 5 in suitable manner in order that. the attaching Vframe may form a rigid and strong support for the carrier-frame 6 of the imple- `6r ment. The carrier frame comprises a number of longitudinally extending bars that are joined by transverse braces or bars to form a rigid structure and the frame is provided With a platform, table, or deck 7 of .suitable 70 lengthn and width to, accommodate one or more men' as required. The frame and decl: are hingedor pivotally supported on the attaching frame by means of transversely extending pin 8, and at'the rear end of the car- 75 rier frame or tiltable frame *are carried a pair of downwardly extending rack arms 9.

hese rack arms are for use in tilting the frame and they co-act with a pair of pinions t l0 on the transversely extending shaft 11, 80 mounted in suitable bearings on the attaching frame, and provided with-a crank handle 12 for turning the shaft and pinions. The rack arms are provided with a series of holes 13 and a selected one of these holes may be used 35 with complementary holesin the attachin frame for the insertion of a bolt or bolts 14- which retain the tiltable frame in adjusted position. The front of the implement may thus be raised or lowered with relation to the surface of the roadway to be cleared in order to insure most efficient service of the implement. l

The tiltable frame in front of the hingeor pivot 8, is provided with a pair of caster wheels 15 that are s aced apart and swiveled to afford a broad caring support for the tiltable frame and to facilitate the steering of the apparatus. The wheels are journaled in arms 16, and as best seen in Figures 7 and 8 w( the arms have a spindle 17 rigid therewith and projecting upwardly therefrom: A swivel head 18 1s provided for the s indle and a cotter pin 19 is used in the spin le to prevent displacement of these parts.

Each swivel head is rigid with a U-shaped oke 20 and each yoke has an attaching racket 21. by means of which the. wheel mount may be bolted to suitable portions of the tiltable frame. The swivel head 18 1s fashioned with a pair of diametrically ai'- ranged trunnions 22 gournaled in bearings of the yoke and one o the truimions of each mount has a pinion 23 thereon. These pmions are turned, from the drivers seat of the vehicle, manually, for swinging the caster, its arms lattei` ,being rigid with the tiltable carrier frame, and the wheels are thus adjusted to com ensate for the changes in relation of the tilta le carrier frame to the road surface..

Each yoke supports a worm screw 24 journaled at 25 therein, and the worm screw of one wheel mount has a bevel gear wheel or pinion 26 that meshes with a complementary pinion 27 on the transversely extendmg shaft 28 that is journaled; in suitable bearings suported from the yokes of the mounts. evel pinion 29 on this cross shaft is engaged by a complementary pinion 30 on the section 31 of an operating bar which may be integral with the worm screw of one' of the mounts. The operating bar is made up of sections and universal joints as 32, and the sections 33 and 34 of the operating bar telescope as indicated in Fi re 1 to'permit adjustment of this sectiona bar. .I At the rear end of the sectional operating bar a second universal joint 35 is Aprovided and the bar may be turned'by means of a hand wheel 36 located in position accessible to the driver of the vehicle.

At the front of the tiltable carrier frame is supported a transversely extending hood 37 which is fashioned with a bottom or horizontal plow or scraper 38 having front V-teeth 39 for engagement with the snow, or ice as the vehicle moves forward. To accommodate the hood to various depths of snow, the upper, front portion of the hood hinged lid 40 having horizontal hinges 41 and a brace 42 hin ed at 43. As indicated by dotted lines in igure 5 the hinged lid may be raised, and in that position it is supported by the hinged brace, the lower free end of which is fastened by a keeper 44 on the rear of the main body of the hood.

At the opposite ends of the hood, and above the plow 38, are provided a air of guards 45 that ila-re outwardly and orwardly of the plow to guide the snow into the hood, and atthe left, forward side of the hoodv a second guard 46 is provided for pushing the snow laterally to the left as the vehicle advances.

Within the hood is carried a rota screw 5 conveyer or excavator 47 with its s aft 48 and head with relation to the yoke, the

is fashioned as a the vehicle and ourarranged transversely of s of the hood. The

naled in suitable bearin rotary screw is designe wardly extending eleft side of the implement and longitudinally of the vehicle. Within the housing is supported an endless belt or chain conveyer 50 having paddles or plates 51 to gather and elevate the snow from the hood tothe upper end of the housing.

-The endless chain conveyer or elevator passes around loose Pulleys or sprockets 52 on the conveyer sha t 48, and o ver complementary sprockets 53that are tight on the sprocket shaft 54 journaled in the upper end of the housing.- The housing is rovided with a discharge spout 55 that is swiveled at 56 so that lthe snow ma be dischar d to either side of the vehic e or otherwise directed from the housing. l

The screw conveyer and the elevator are operated from a motor 57 of suitable ty to convey the snow through the hood to an u vhousing 49 arranged at t that is supported on the deck of the tiltab e A loose on the screw conveyer shaft.v The screw conveyer shaft 48 is driven directly from the jack shaft or operating shaft 54 by means of an outside sprocket lwheel 60, chain 61 and the sprocket wheel 62 on the shaft 48, thus permitting the screw conveyer and the'elevator to be driven at relatively different speeds for conveying and elevating the snow. The lower end of the chain 61 and the sprocket wheel 62 are protected from the snow by the guard 46 which directs the snow away from t ese parts as the implement advances. The motor 57 may be an electric motor or an internal combustion engine, or other means may be used for supplying the power to the two conveyers.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is v -1. The combination with an attaching frame of a hinged carrier frame, means for adjusting the carried frame and retaining means therefor, a hood mounted on the carrier frame and a plow projectin forward of the hood, said hood having a ifed lid and a brace for holding the 11d in adjusted osition, a rotary excavator supported within the'hood, an endless elevator, and means for operating said excavator and elevator.
